Gunbus is go

German engineer Clemens Leonhardt has followed through on his wild promises to build the world's biggest road bike, called the Gunbus.

Everything about the 3.47 metre long machine is oversized, from the airliner tyres to the huge 6728cc (410ci) V-twin fuel-injected powerplant. Weight is a claimed 650kg.

We've yet to come across a test ride on the thing, and can only imagine what you'd have to do if you had the misfortune to tip it over in your driveway. Call in a crane, perhaps?

For those who have reservations about riding it solo, Leonhardt has promised to develop a sidecar.

Pricing has yet to be announced, but by all accounts Leonhardt is determined to go into production.
